Sulphur Dioxide Analyzer

The AAQMS-500 Sulphur Dioxide (So2) analyser delivers precise and reliable performance at excellent value. It uses proven UV Fluorescence technology with standard range 0~100 ppb and 0.5 ppb detectable limit. It is CPCB / USEPA approved method and meets the latest specifications of National Ambient Air Quality Standards.

UV Source

The Pulsing of the UV source lamp serves to increase the optical intensity where by a greater UV energy throughput and lower detectable concentration are realized.

Key Features
  • Critical orifices provide flow stability.
  • Various Outputs Include Ethernet and Rs232.
  • User Friendly interface with Large Screen.
  • Multi-Tasking software allows viewing text variables while operating.
  • Internal Data logging with 1 min to 365 days Multiple averages.
